Note that the resourcePath option can either in specified in the URI as a part of the URI path, as an endpoint option ?resourcePath=<resource-path> or as a header value CamelOlingo2.resourcePath. The OData entity key predicate can either be a part of the resource path, e.g. Manufacturers('1'), where '1' is the key predicate, or be specified separately with resource path Manufacturers and keyPredicate option '1'.

The following route reads top 5 entries from the Manufacturer feed ordered by ascending Name property.
from( "direct:..." ) .setHeader("CamelOlingo2.$top", "5" ); |
The following route reads Manufacturer entry using the key property value in incoming id header.
from( "direct:..." ) .setHeader("CamelOlingo2.keyPredicate", header("id") ) |
The following route creates Manufacturer entry using the java.util.Map<String, Object> in body message.
The following route polls Manufacturer delta feed every 30 seconds. The bean blah updates the bean paramsBean to add an updated !deltatoken property with the value returned in the ODataDeltaFeed result. Since the initial delta token is not known, the consumer endpoint will produce an ODataFeed value the first time, and ODataDeltaFeed on subsequent polls.
